Great question, to become an Electrician you first have to start as a Journeyman.
To begin training as a journeyman you must first have a high school diploma (or the equivalent such as a GED).
Next, complete a pre-apprenticeship electrician-training program at a local trade, technical, or vocational school.
Once you complete the training you would apply for an electrician apprenticeship and, if required, register as an electrician apprentice or trainee in your state.
After completing a four- or five-year apprenticeship under the guidance of a master or journeyperson electrician you apply for your electrician license or become certified in your state and/or municipality, which may involve passing an exam.
